Incilius tacanensis (common name: Volcan Tacana toad) is a species of toad in the family Bufonidae. It is found in western Guatemala and eastern Chiapas (Mexico). Its name refers to Volcán Tacaná, its type locality.[1] Its natural habitat is premontane tropical forest. It is assumed to be a stream breeder. It is a rare species threatened by habitat loss, and potentially, chytridiomycosis.
